2.5-A, 5-A, 35-VMAX VDD FET and IGBT Single Gate Driver - UCC27531


2.5-A, 5-A, 35-VMAX VDD FET and IGBT Single Gate Driver


The UCC2753x family of devices are single-channel, high-speed, gate drivers capable of effectively driving MOSFET and IGBT power switches by up to 2.5-A source and 5-A sink (asymmetrical drive) peak current. Strong sink capability in asymmetrical drive boosts immunity against parasitic Miller turn-on effect. The UCC2753x device can also feature a split-output configuration where the gate-drive current is sourced through OUTH pin and sunk through OUTL pin. This pin arrangement allows the user to apply independent turn-on and turn-off resistors to the OUTH and OUTL pins respectively and easily control the switching slew rates.

The driver has rail-to-rail drive capability and extremely small propagation delay typically 17 ns.

The input threshold of UCC2753xDBV is based on TTL and CMOS compatible low-voltage logic, which is fixed and independent of VDD supply voltage. The 1-V typical hysteresis offers excellent noise immunity.

The driver has EN pin with fixed TTL compatible threshold. EN is internally pulled up; pulling EN low disables driver, while leaving it open provides normal operation. The EN pin can be used as an additional input with the same performance as the IN, IN+, IN1, and IN2 pins.
